The Datamaster is an [[All-in-one PC|all-in-one]] computer with text-mode [[Cathode-ray tube|CRT]] display, keyboard, processor, memory, and two 8-inch [[floppy disk]] drives in one cabinet.<ref name=":0" /> The processor is an 8-bit [[Intel 8085]]<ref name="auto">{{Cite web|url=http://www.oldcomputers.net/ibm5322.html|title=IBM 5322 System/23 Datamaster computer|website=www.oldcomputers.net}}</ref> running at 6.14 MHz,<ref name="bitspassats" /> with [[bank switching]] to manage 128&nbsp;KB of memory.{{r|bradley199009}} Available RAM was 32&nbsp;KB (expandable to 128&nbsp;KB<ref name="auto1">{{cite web | url=https://www.oldcomputers.es/ibm-systems23-5322/ | title=IBM System/23 Datamaster }}</ref>), and the machine had four internal expansion slots.<ref name="auto"/> It could display 80&nbsp;× 24 characters of text (each character with 8&nbsp;× 14 pixels) with 128 possible characters, on a built-in 12" green phosphor CRT.<ref name="auto"/><ref>{{Cite book |url=https://www.nf6x.net/wp/wp-content/uploads/2014/10/IBM-5322-Service-Library-Volume-1.pdf |title=IBM System/23 Service Library - Volume 1 : IBM 5322 Computer Service Manual |publisher=IBM |year=1980 |pages=4–21}}</ref>

The intention of the Datamaster was to provide a computer that could be installed and operated without specialists. A [[BASIC]] interpreter was built-in to the system. IBM decided to merge the Datamaster's BASIC implementation with [[System/34 BASIC]], which reportedly delayed the Datamaster by almost a year.<ref name="bradley199009">{{cite news | url=https://archive.org/stream/byte-magazine-1990-09/1990_09_BYTE_15-09_15th_Anniversary_Summit#page/n451/mode/2up | title=The Creation of the IBM PC | work=BYTE | date=September 1990 | accessdate=2 April 2016 | author=Bradley, David J. | pages=414–420}}</ref> When introduced, a single-screen Datamaster sold for around {{USD|9000|1981}}.
